[0003] The main technical problem this application addresses is to provide a protective sleeve that improves the support effect of the protective sleeve.

[0004] To solve the above-mentioned technical problems, this application adopts a technical solution: a protective cover, the protective cover comprising: a protective shell having a support surface and a back surface disposed opposite to each other, the support surface being used to support a flat plate, and the back surface having a receiving groove; a flip cover rotatably connected to the protective shell, used to cover the support surface of the protective shell or to flip over to the back surface of the protective shell; and a support member disposed in the receiving groove and rotatably connected to the protective shell, the support member being used to extend from the receiving groove to abut against the flip cover when the flip cover is flipped over to the back surface of the protective shell, and to support between the protective shell and the flip cover.

[0005] The support member has a first end and a second end that are arranged opposite to each other. The first end is rotatably connected to the wall of the receiving groove, and the second end can rotate relative to the back of the protective housing along the first end. The outer side of the flip cover has a plurality of spaced grooves that are adapted to the second end of the support member. When the flip cover is flipped to the back of the protective housing, the second end of the support member disengages from the receiving groove to abut against any of the grooves on the flip cover.

[0006] The bottom wall of the receiving groove is provided with a first magnetic element, and the second end of the support member is provided with a second magnetic element. When the support member is located in the receiving groove, the first magnetic element and the second magnetic element attract each other.

[0007] The protective housing also has an operating groove on its back side that connects to the receiving groove. The operating groove allows external forces acting on the second end of the support member to disengage from the receiving groove.

[0008] The protective housing has a positioning part at the corner, which is used to correspond to the foot pad on the flat plate. The positioning part is a positioning hole that penetrates the support surface and the back side along the thickness direction of the protective housing, or a positioning groove that is provided on the support surface along the thickness direction of the protective housing.

[0009] The positioning part is a positioning hole that penetrates the support surface and the back surface along the thickness direction of the protective shell. The end of the foot pad of the flat plate can be flush with the back surface or protrude beyond the back surface.

[0010] The protective housing has a circumferentially arranged limiting part protruding on its supporting surface, which is used to wrap around the side wall of the flat plate.

[0011] The limiting part has a notch, and part of the sidewall of the plate is exposed at the notch.

[0012] The support surface is covered with a buffer pad, and the edge of the buffer pad is located inside the limiting part.

[0013] The protective housing has a third magnetic element inside the back side. The protective cover also includes a buckle connected to one side of the flip cover. The buckle has a fourth magnetic element inside. The buckle is used to wrap around to the back side of the protective housing when the flip cover is closed on the support surface of the protective housing, so that the fourth magnetic element attracts the third magnetic element.

[0014] Beneficial effects: This application provides a retractable support member on the back of the protective case. When the tablet needs support, the support member rests directly against the flip-up cover, providing stable support and effectively reducing the risk of the tablet tipping over or shaking during use. Furthermore, when not in use, the support member can be completely retracted into the protective case, without affecting its portability. Attached Figure Description

[0019] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4This application provides a protective case 100 for storing a tablet 200. It is understood that the protective case 100 can also store other electronic devices, such as mobile phones or writing tablets. The protective case 100 includes a protective shell 10, a flip cover 20, and a support member 30. The protective shell 10 serves as the main structure of the protective case 100, used to fix and protect the tablet 200. The protective shell 10 and the flip cover 20 are rotatably connected to expose or protect the tablet 200 inside the protective case 100. The support member 30 is rotatable relative to the protective shell 10 to support the tablet 200.

[0020] Specifically, the protective housing 10 has a support surface 11 and a back surface 12 arranged opposite to each other. The support surface 11 supports the plate 200, and the back surface 12 has a receiving groove 121. The support surface 11 on the protective housing 10 is the side facing the plate 200, used to fit and support the plate 200. The back surface 12 is the outer surface of the protective housing 10, directly exposed to the outside, for contact with the outside world or to cooperate with other components. The receiving groove 121 on the back surface 12 is used to store the support member 30, hiding the support member 30 when not in use, keeping the overall appearance of the protective housing 100 neat.

[0021] The flip cover 20 is rotatably connected to the protective housing 10, and is used to cover the support surface 11 of the protective housing 10, or to flip onto the back surface 12 of the protective housing 10. That is, the flip cover 20 and the protective housing 10 can cooperate to achieve two states of the protective cover 100. When the flip cover 20 is in the state of covering the support surface 11, the flip cover 200 covers the screen of the tablet 200, realizing the closed protection state of the tablet 200. When the flip cover 20 is flipped onto the back surface 12 of the protective housing 10, it can be used to cooperate with other components (such as the support member 30) to form a bracket to support the tablet 200 inside the protective housing 10.

[0022] The support member 30 is disposed in the receiving groove 121 and is rotatably connected to the protective housing 10. The support member 30 is used to extend out of the receiving groove 121 to hold the flip cover 20 when the flip cover 20 is flipped to the back side 12 of the protective housing 10, and is supported between the protective housing 10 and the flip cover 20.

[0023] The support member 30 extends and abuts against the flip cover 20, providing support between the protective housing 10 and the flip cover 20, forming a stable triangular support system. This allows the flat plate 200 inside the protective sleeve 100 to be placed at an angle relative to the workbench for ease of use. Simultaneously, the flip cover 20, in bracket mode, acts as part of the support, increasing structural stability.

[0024] Meanwhile, when not in use, the support 30 can be completely stored in the receiving groove 121 of the protective shell 10, without affecting the overall aesthetics and portability of the protective cover 100, and without increasing the volume of the protective cover 100.

[0025] In actual use, when the flip cover 20 is placed on the support surface 11, it can protect the tablet 200 and make it easy to carry. When it is necessary to switch to the stand mode, the support member 30 hidden in the receiving groove 121 is taken out and flipped onto the flip cover 20 on the back 12 of the protective shell 10 to form a stable tilt angle.

[0026] In the aforementioned protective case 100, a retractable support member 30 is provided on the back 12 of the protective shell 10. When the tablet 200 needs support, the support member 30 directly abuts against the flip cover 20 that has been flipped to the back 12, providing stable support for the tablet 200 and effectively reducing the risk of the tablet 200 tipping over or shaking during use. At the same time, when not in use, the support member 30 can be completely stored inside the protective shell 10, without affecting the portability of the protective case 100.

[0027] Please continue reading. Figure 1 , Figure 2 and Figure 3 In one embodiment, the protective cover 100 further includes a connecting portion 40, which is connected between the flip cover 20 and the protective housing 10. The flip cover 20 rotates along the connecting portion 40 to cover the support surface 11 of the protective housing 10 or flips to the back surface 12 of the protective housing 10.

[0028] Please refer to the following: Figure 1 , Figure 3 and Figure 4 In one embodiment, the support member 30 has a first end 31 and a second end 32 disposed opposite to each other. The first end 31 is rotatably connected to the wall of the receiving groove 121. The first end 31 serves as the rotation fulcrum of the support member 30, allowing the support member 30 to unfold outward from the receiving groove 121. The second end 32 can rotate relative to the back surface 12 of the protective housing 10 along the first end 31, that is, under the drive of the first end 31, the second end 32 can move relative to the back surface 12 of the protective housing 10.

[0029] The outer side of the flip cover 20 is provided with a plurality of spaced grooves 21. The grooves 21 are adapted to the second end 32 of the support member 30. When the flip cover 20 is flipped to the back 12 of the protective shell 10, the second end 32 of the support member 30 disengages from the receiving groove 121 to abut against any groove 21 on the flip cover 20. Each groove 21 serves as a positioning point for engaging with the second end 32 of the support member 30 to achieve angle locking and adjust the tilt angle of the flat plate 200 in the protective cover 100.

[0030] Please refer to the following: Figure 1 and Figure 3In one embodiment, the groove 21 may be covered with a friction layer (not shown) to increase the coefficient of friction between the second end 32 of the support member 30 and the groove wall of the groove 21, thereby improving the stability of the support member 30 supported between the protective shell 10 and the flip cover 20.

[0031] Please continue reading. Figure 1 and Figure 3 In one embodiment, a damping element (not shown) may be provided between the first end 31 of the support member 30 and the wall of the receiving groove 121. The damping element is used to generate a damping force to maintain the predetermined angle after the first end 31 of the support member 30 rotates relative to the protective housing 10 to a predetermined angle. The damping element can improve the stability of the support member 30 during the rotation process.

[0032] Please continue reading. Figure 1 and Figure 3 In one embodiment, a torsion spring or spring sheet structure may be added between the first end 31 of the support member 30 and the groove wall of the receiving groove 121, so that the support member 30 can automatically pop out, improving the ease of use of the protective cover 100.

[0033] Please continue reading. Figure 1 and Figure 3 In one embodiment, the bottom wall of the receiving groove 121 is provided with a first magnetic element 122, and the second end 32 of the support member 30 is provided with a second magnetic element 33. When the support member 30 is located in the receiving groove 121, the first magnetic element 122 and the second magnetic element 33 attract each other. When the support member 30 is retracted, the second magnetic element 33 aligns with the first magnetic element 122 and generates a magnetic attraction force, realizing the automatic return of the support member 30 to its original position, and simultaneously locking the support member 30 within the protective housing 10.

[0034] When the support member 30 retracts inward and returns to the receiving groove 121, the second magnetic member 33 on the support member 30 approaches the first magnetic member 122 on the bottom wall of the receiving groove 121, and the two generate an attraction between them, which firmly fixes the support member 30 in the storage position, thereby reducing the risk of the support member 30 accidentally popping out due to shaking, falling or accidental contact.

[0035] In one embodiment, if the first magnetic element 122 is a magnet, the second magnetic element 33 can be an ferrous metal sheet (to be attracted), or the first magnetic element 122 and the second magnetic element 33 can be magnets with opposite magnetic poles to achieve mutual attraction. The specific configuration depends on the requirements and is not limited here.

[0036] Please continue reading. Figure 1 and Figure 3 In one embodiment, the back side 12 of the protective housing 10 is also provided with an operation groove 123 that connects to the receiving groove 121. The operation groove 123 allows external forces acting on the second end 32 of the support member 30 to disengage from the receiving groove 121.

[0037] Specifically, the operating groove 123 serves as a channel for external intervention, allowing the user to touch and push the second end 32 of the support member 30 with their fingers or simple tools to gently push or pry the second end 32 of the support member 30 outwards, so that the support member 30 can be disengaged from the receiving groove 121 for support.

[0038] In one embodiment, the shape of the operating groove 123 can be straight, arc-shaped or U-shaped, depending on the requirements, and is not limited here.

[0039] Please refer to the following: Figure 1 , Figure 2 and Figure 4 In one embodiment, a positioning part 13 is provided at the corner of the protective housing 10, which is used to correspond to the foot pad 201 on the flat plate 200. The positioning part 13 is a positioning hole (not shown) that penetrates the support surface 11 and the back surface 12 along the thickness direction of the protective housing 10, or a positioning groove (not shown) provided on the support surface 11 along the thickness direction of the protective housing 10.

[0040] Specifically, the positioning part 13 on the protective housing 10 can improve the accuracy of the protective sleeve 100 when assembling the flat plate 200, so that the flat plate 200 can be automatically aligned and accurately positioned in the protective housing 10, and reduce the risk of misalignment or shaking of the flat plate 200 relative to the protective housing 10.

[0041] Please refer to the following: Figure 1 , Figure 5 and Figure 6 In one embodiment, the positioning part 13 is a positioning hole that penetrates the support surface 11 and the back surface 12 along the thickness direction of the protective housing 10. The end of the foot pad 201 of the plate 200 may be flush with the back surface 12 or protrude beyond the back surface 12. When the plate 200 is inserted into the protective housing 10, the foot pad 201 is embedded and passes through the positioning hole, and the bottom of the foot pad 201 is slightly exposed on the back surface 12 of the protective housing 10, or is just flush with the back surface 12 of the protective housing 10.

[0042] In one embodiment, the foot pad 201 of the plate 200 has an inverted T-shaped structure. When the foot pad 201 of the plate 200 is flush with the back surface 12 of the protective housing 10, the cross-section of the positioning hole can be set to match the inverted T-shape of the foot pad 201. When the foot pad 201 of the plate 200 is exposed on the back surface 12 of the protective housing 10, the cross-section of the positioning hole can be set to an I-shaped structure to hold the foot pad 201 located in the positioning hole.

[0043] In one embodiment, the positioning part 13 is a recessed positioning groove provided at the corner of the support surface 11 of the protective shell 10. The depth of the positioning groove is slightly greater than the height of the foot pad 201, and the shape matches the foot pad 201. After the flat plate 200 is placed in, the foot pad 201 is embedded in the positioning groove and is completely wrapped by the positioning groove, reducing the risk of the foot pad 201 directly contacting the table and causing wear or falling off.

[0044] In one embodiment, the foot pads 201 of the flat plate 200 are made of silicone, rubber or other soft materials, depending on the requirements, and are not limited here.

[0045] Please refer to the following: Figure 2 and Figure 4 In one embodiment, a positioning part 13 is provided at each of the four corners of the protective shell 10 to correspond one-to-one with the foot pads 201 at the four corners of the flat plate 200.

[0046] Please continue reading. Figure 2 and Figure 4 In one embodiment, a limiting portion 50 is provided on the support surface 11 of the protective housing 10 and is arranged in a surrounding manner. The limiting portion 50 is used to wrap around the side wall of the flat plate 200. The limiting portion 50 is a raised frame structure that extends from the support surface 11 in a direction away from the back surface 12, and is arranged in a surrounding manner along the inner edge of the protective housing 10 to form a concave receiving area to accommodate the flat plate 200, thereby improving the protective cover 100's wrapping ability, impact resistance and overall stability of the flat plate 200.

[0047] In one embodiment, the limiting part 50 is an integrally formed structure disposed on the support surface 11 of the protective housing 10. In other embodiments, the limiting part 50 may also include multiple sub-limiting parts that are continuously or intermittently distributed along the inner edge of the protective housing 10, depending on the requirements, and is not limited here.

[0048] Please continue reading. Figure 2 and Figure 4 In one embodiment, the limiting part 50 is provided with a notch 51, and part of the side wall of the plate 200 is exposed at the notch 51.

[0049] In one embodiment, the limiting part 50 may also be provided with other functional notches (not shown), which correspond to the functional modules (such as charging port, volume buttons, power button, headphone jack, etc.) on the side wall of the tablet 200, so that the user can operate the tablet 200 through the functional notches.

[0050] In one embodiment, the edge of the notch 51 is chamfered to improve the security of the protective cover 100.

[0051] Please continue reading. Figure 2and Figure 4 In one embodiment, the support surface 11 is covered with a buffer pad 14, and the edge of the buffer pad 14 is located inside the limiting portion 50. The buffer pad 14 can reduce the risk of the protective housing 10 scratching the surface of the flat plate 200, thereby improving the product reliability of the protective cover 100.

[0052] In one embodiment, the buffer pad 14 can completely cover the support surface 11 and make openings in the positioning part 13 at the corner of the protective housing 10, or the buffer pad 14 can avoid the corner area of ​​the protective housing 10. The specific configuration is determined according to the requirements and is not limited here.

[0053] Please refer to the following: Figure 1 , Figure 2 and Figure 4 In one embodiment, a third magnetic element 60 is provided inside the back surface 12 of the protective housing 10. The protective sleeve 100 also includes a latch 70, which is connected to one side of the flip cover 20. A fourth magnetic element 71 is provided inside the latch 70. The latch 70 is used to wrap around to the back surface 12 of the protective housing 10 when the flip cover 20 is closed on the support surface 11 of the protective housing 10, so that the fourth magnetic element 71 and the third magnetic element 60 are attracted to each other. The magnetic attraction between the latch 70 and the protective housing 10 further ensures the stability of the flat plate 200 inside the protective sleeve 100.

[0054] In other embodiments, the protective housing 10 and the buckle 70 can also be detachably connected by snaps, clips or Velcro, depending on the requirements, and are not limited here.
